range-diff: offer --left-only/--right-only options
When comparing commit ranges, one is frequently interested only in one
side, such as asking the question "Has this patch that I submitted to
the Git mailing list been applied?": one would only care about the part
of the output that corresponds to the commits in a local branch.
To make that possible, imitate the `git rev-list` options `--left-only`
and `--right-only`.
